jQuery keypad plugin - change position/size of keypad popup

I'm using the jQuery keypad plugin. It attaches a keypad to an input box. However, the keypad appears right next to the input box. I would like it to appear at the bottom of the screen, far from the input box to which it is attached. Is there an easy way to achieve this?

I browsed through the source, but I'm not sure my JavaScript/jQuery knowledge is up to the level required to try to modify this. I suppose I could use jQuery to dynamically change the CSS positioning and width of the keypad-popup. Would this be the easiest way for me to proceed?
